copied!<p>I couldn't find <code>NSRunningApplication</code> in the iOS (public or private) 5.0 headers (I'm pretty sure I checked everywhere, but I could be wrong ...)</p> <p>There's probably multiple ways to do this, but one of these should work ...</p> <p>First, get information about the running processes. If you can't get the bundle ID, but can get the <strong>path</strong> to the app, then that's good enough. You could do that in one of a few ways:</p> <p><strong>1)</strong> <a href="https://stackoverflow.com/questions/8275578/how-to-get-information-about-free-memory-and-running-processes-in-an-app-store-a">See this answer on stack overflow</a> or maybe <a href="https://stackoverflow.com/a/8278785/119114">this one</a>. I'm not sure the executable path is available with these techniques ... I didn't explore them in depth.</p> <p><strong>2)</strong> You <strong>can</strong> get process information through the <code>ps</code> shell command. For example, with a <code>ps -Aef</code> command at the command line:</p> <pre><code>iPhone4:~/Applications/8AA99EA8-9CFC-4C17-9BD1-7C2812EDAAD4/Starbucks.app mobile$ ps -Aef UID PID PPID C STIME TTY TIME CMD 501 281 1 0 0:00.00 ?? 1:02.39 /Applications/MobilePhone.app/MobilePhone 501 282 1 0 0:00.00 ?? 2:26.40 /Applications/MobileMail.app/MobileMail 501 479 1 0 0:00.00 ?? 5:45.01 /Applications/MobileSafari.app/MobileSafari 501 490 1 0 0:00.00 ?? 0:45.62 /Applications/Music~iphone.app/Music~iphone 501 912 1 0 0:00.00 ?? 0:17.65 /var/mobile/Applications/8AA99EA8-9CFC-4237-9BD1-7C2812AAAAD4/Starbucks.app/Starbucks 501 1933 1 0 0:00.00 ?? 0:51.72 /var/mobile/Applications/9962D9AE-087C-4D2E-A6AB-151230DBCDB09/Skype.app/Skype 501 2106 1 0 0:00.00 ?? 1:11.68 /var/mobile/Applications/20DCED79-B1EE-48F4-B3E1-75E9C25A0908C/Netflix.app/Netflix 501 2259 1 0 0:00.00 ?? 0:03.83 /Applications/Stocks.app/Stocks 501 2292 1 0 0:00.00 ?? 0:07.05 /var/mobile/Applications/33713030-9D3D-4BAC-8182-282973B2E5E0/ZillowMap.app/ZillowMap 501 2568 1 0 0:00.00 ?? 0:12.91 /var/mobile/Applications/55216130-10D8-498C-B477-AD18A4982E18/eBay.app/eBay 501 2587 1 0 0:00.00 ?? 0:05.10 /var/mobile/Applications/2A8DEAAD-8244-45C0-BEA9-20DA290B0117/Moviefone.app/Moviefone </code></pre> <p>I removed some of the output, but you can see some of the apps running (*.app). </p> <p>So, in your app, you could run <code>"ps -Aef >> /var/mobile/Library/MyAppName/ps.txt"</code> with a <code>system</code> or <code>exec</code> call, sending the output to a temporary file. Then, parse that file to get the results.</p> <p><strong>3)</strong> I also found a copy of the Darwin open source online, and hacked it up a little to collect this kind of data into a C string buffer, that can be parsed programmatically. Get the header and .c file here:</p> <p><a href="http://pastebin.com/EDWtGrhc" rel="nofollow noreferrer">darwin.c</a></p> <p><a href="http://pastebin.com/kiNEU669" rel="nofollow noreferrer">darwin.h</a></p> <p>Include those two files in your Xcode project, and <code>#include "darwin.h"</code>. Then, use it like so:</p> <pre><code>OS_initialize(); size_t buffSize = 20000; // you may need to increase this! char buffer[buffSize]; int bytes = OS_get_table(buffer, buffSize); if (bytes > 0) { self.textView.text = [NSString stringWithCString: buffer encoding: NSASCIIStringEncoding]; } </code></pre> <p>Now that you have the apps' install locations, open up the Info.plists under those directories</p> <pre class="lang-objc prettyprint-override"><code>NSString* filename = @"/var/mobile/Applications/8AA99EA8-9CFC-4237-9BD1-7C2812EDAAD4/Starbucks.app/Info.plist"; NSDictionary* dict = [[NSDictionary alloc] initWithContentsOfFile: filename]; NSString* bundleID = [dict valueForKey: @"CFBundleIdentifier"]; </code></pre> <p>and read their bundle IDs.</p> <p>In order to make this work, you may need to gain root privileges for your app.</p> <p><a href="https://stackoverflow.com/a/8796556/119114">See here on how to do that</a>.</p>
